SADDLE FOR TOP-ROLLS'OF SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 284,040, dated August 2S, 1883.

Application filed July 8, 1882.

To all whom t may concern Be it known that I, JOHN l?. MoGUINNEss, of Providence, in the State of Rhode Island, have invented an Improvement in Saddles `for the Top-Rolls of Spinning-lVIachines, of which the following is a specieation. v

The nature of my invention consists in the combination of one ofthe sections of the saddle, provided with an inclosed space or slot, with the other section of the same, provided with a transverse pin passing loosely through the inclosed space or slot, the pin and slot serving to form avariable joint; and in the combination therewith of oil-chambers and oil-outlets adapted to receive wicks for applying oil to the bearings of the rolls. v

,Figure 1 represents a side elevation of my improved saddle in working position upon the saddle-bearings of the top-rolls. Eig. 2 represents a central longitudinal section of the same. Fig. 3 represents a plan view of the under side of the front portion of the saddle. Eig. 4 represents a top view of the rear portion of the saddle. Fig. 5 represents a transverse section taken in the line :c a: of Fig. l.

Heretofore the saddles for top-rolls have been made in two parts, separate from each other, and in their use there is liability of dropping the parts, and also loss of time in handling on the part of the operatives in the mill. In my improvement I join the two parts of the saddle in one by an extensible connection, whereby suitable provision is made for the proper adjustment of the saddle to iit the rolls, and danger of separation and loss of the parts is avoided.

In the accompanying drawings, A is the front and B the rear portion oi' the saddle. C is the holding-stirrup, and D D D2 the toprolls, upon the central bearings, d cl/ d2, of which the saddle is made to rest.

rlhe front portion, A, of the saddle, is provided with an oil-chamber, a, open at the top, and provided at the bottom with the oil-holes b and c, into which, extending from one hole to the other along the bottom of the chamber a, is inserted the wick e, which allows the oil in the chamber a to flow very gradually to the bearing d of the front top-roll, D, and also to the open oil-chamber f in the upper part of the No model.)

rear portion, B, of the saddle. At the opposite extremities of the oil-chamber f are drilled the holes g and 71 into which is inserted the wick i, passing from one hole to the other along the bottom ofthe oil-chamber f, and allowing the oil in the` chamber to gradually percolate to the bearing d of the rear top-roll, D', and to the bearing d2 of the middle roll, D.

The rear end of the front portion, A, of the saddle is cut away at the sides to admit the ears j j ofthe rear section B, leaving a central longitudinal rib, k, which is adapted to pass loosely into the space between the ears j j. In

a vertical plane passing through the longi-4 tudinal axis of the section A is secured the elongated wire staple Z, the ends of which are attached to the metal of the section A when in the mold, thus securing the same in a permanent manner by insert-ion into the molten metal.

Transversely of the rear section, B, at the ears j j, are drilled the holes m m, through which is passed the wire pin a, which may be secured within the holes m by heading over the ends of the wire. rIhe wire pin a is made to pass loosely through the elongated space o between the inner surface of the staple l and the adjoining surface of the rib 7c, thus all owing the pin n to be moved transverselyof its length from one end of the space 0 to the other.

The section A is provided at its under side and forward end with the transverse circular groove p, adapted to rest upon the bearing d of the front roll, D, and the section B is provided at` its under side and rear end with the transverse `circular groove q, adapted to rest upon the bearing d of the rear roll, D, and the space o, made in the connection between the two sections, will allow for any required variation in the distance between the bearings d and d of the front and rear rolls, the sections A and B being adapted to slide one upon the other through. the limit of the space 0 within the staple Z.

IVhen the saddle is removed for the purpose of cleaning the rolls, both ofthe parts A and B are moved together, which results in a saving of time over the arrangement now in use, where the parts A and B are unconnected to IOO each other and require separate handling, and the danger of dropping the saddles into the inachine, as at present, is materially lessened.

I do not, of course, limit my invention to the employment of a wire staple for vinelosing the space o, adapted to receive the transverse pin n, for the reason that a suitable slot may be readily formed by other means, as*Y by setting a core in the mold for casting; and it is also to be understood that the slot and transverse pin may be placed upon either of the two parts of the saddle, respectively, although I have preferred'to locate the pin in the rear section of the saine.

I claim as niy invention- 1. In a saddle for top-rolls, the front and rear sections of which are permanently connected to each other, the combination of one of the sections7 provided with an inelosed space or slot, With the other section, provided with a transverse pin passing loosely through the inelosed space or slot, the pin and slot serving to form a variable joint, whereby the permanently-connected parts may be properly adjusted to the rolls, substantially as described.

2. In a saddle for top-rolls, the combination of the rearseetion, B, provided With the transverse pin n, and the front section, A, provided at its rear with an inelosed space adapted to forni an extensible joint With`the trans-v verse pin n, With the oil-chambers a and f, and oil-outlets b c g h, adapted to receive the Wicks e i, substantially as described.
